I DEVICE FOR APPLYING PASTE TO MATERIALS Filed "July 24, 1953 lo? 6l:n."l 76 .3? 64039 100% 62 :gg f 6a ATTORN EYS Patented Jan.` 1, 1935 InvIo n n. Islaam i This invention relatestoa-deVicefor applying paste toone faceof variouskinds'of materiaL-` `An object of theinvention is-'thepro-vision vof a device'for applying paste to one faceoffva'rious typesof materials inI whic'hiafcylinderis emf eling carrier the pasted'surface will be "out" of paste to one face of various kindsOfmaterials` in which a container carrying! pasting material has astepped portion forming af'tablefor feeding materials to be pastedacross the outer exposed surface of a revolving cylinder which ispartlyim- `mersed in the pasting solution, the cylinder being located inan opening formed in the` top of the lower stepped portion and anlintermediate i veritical wall-betweeny the topsof theupper and ilowersections so that the exposedvyportiontof the cylinder will be inlinewith theftopor table "ofthe upper stepped section,meansi being eniployedfor reversing the pasted faceofthe'material so that said face willremain out of contact n `with a traveling carrier which removes thematerials away from the pasting machine.

A further object of th invention is the provision of a device forsupplyingpaste to'one face of materials in which a container isremployed`having an openingl toreceive a" cylinderwhich is revolved in thepastingsolution in the container,

i means beinglemployed for lmaintaining aprede- `changes andmodifications whichrshall denne no 50 material departure from` thesalienti features of the invention asfexpressed inithe' appended claim.

Infthe drawing: i "",Figure 1 4is a plan `view of a pasting machineconstructed in accordance with theprinci les of my invention,` andFigure 2 is `a vertical section of the pasting machine "taken'alongtheline 2-2 ofFig. 1.`

Referring more particularly tothe drawing,` designates a base member orworktable upon which the pasting machine is secured. Aconianiiatibnnly.241.19%, sferiailNo.- 682,003 I n (el. sit-151) OFFICE;N I

vtainer 11 is supported on the table and is adapted to be suppliedwith apasting solution and this solution is maintained at apredetermined-level as indicated bythe dotted line 12,` shown in Fig.

'2. Any form of paste may be employed, dependi ing upon thelmaterialsemployed and the use of thewmaterials. n the present instance, however,the pasting `machine is employed for vsupplying latex or other similarform of pasting mat `terials toinner soles, box toes, counters, andvarious other types of fabrics used principally in `shoe factories. y

The container is composed of an upper stepped section 13and a lowerstepped section 14. A top 15 of the upper section forms a tabletoreceive Vand feed the materials across the top of a revolving, pastingcylinder 16. `The lower section 14l fsJprovided-with-a -top 17 and ahingedly mounted door 18.` The door 18 closes an opening l through whichthe pasting `material is adapted to be supplied tothe container 11.`Thebottom 19 ofthe container is provided with a drain plug 20.`Anintermediate vertical Wall 21 is"located between the tops 15 and `17.i

`The top 17 of the lower-section 14 is provided with an` opening 25 andthe intermediate wall 21 is 'also provided with an opening 26` through`whichprojects a portion of the .cylinder 16, and theinner edge 27 ofthe top or table 15 is beveled Aadjacent; the outer surface ofthecylinder 16 faridlwhere lsaid cylinder `projects through the opening-26.-l l A shaft `28 is mounted in bearings29 formed '-on" the `top17. Iheshaftis considerably longer 'than-the cylinder 16 so that the' bearingswill libe located away from the pasting solution in-the fcontainer; Theshaft 28 is driven by meansof Ya belt 30,v a pulley 31 anda pulley`33onthe shaft 32. The shaftz'isdriven by means of a pulley 32a andfa `belt34 which extends *to a pulley driven by an4 electric motor, not shown. 1giftBrackets36 are supported from the top 17 of the lowersection l4fandlare provided with an fopen bearing37to receive theends of an axle 38"carrying a roller 39. It will be noted that the roller `is spaced fromthe cylinderlG a 'sufcient di'st'arice to engage the material pastedbetween the roller 'and the cylinder and the elongated or`openbearings37 permit the roller to apply pressure to the material sovthat it "will receive the ",paste from `the surface of `the cylinder 16while permitting `materials of variousthicknesses to pass between theroller and the revolving cylinder. y Af pair ofvertically` disposedguides 40 are vmounted upon the table 15 and are held in place bystraps41 having slots-42 which `receive bolts 43 threaded into the top15. By this arrangement the guides 40 may be moved towards or away fromeach other to accommodate material of diftder 16 and lightly restsferent widths. The outer ends of the guides 40 are flared outwardly, asshown at 44.

A scraper 50 is carried in tracks 51 secured to the'side walls of. thecontainer .-1-1 fandfhasea knife edge Z1atlapted t'o be located"adjacent the outer surface of the revolving cylinder 16 -in order toremove a predetermined quantity of past-q Ying solution from the surfacesothatthe proper amount of paste will be supplied-tolthe'materials A nut53 is secured to the scraper 50 and receives a bolt 54 having amanipulating knob55-located externally of the container 11. A iiange 56on the bolt and a collar 57 upon-oppositesides-of an Y end wall of thecontainer 11 permits rotation of the bolt 54 but prevents longitudinalmovement 'ofsaid-bolt.. n g

The rscraper j 50 is jprovided 'with extensions 58 rwhich engage`theiernds "of the cylinder ;1 6 and 'remove l'any pastev from fsaida'ends.
